Oral Rehydration Solutions (ORS) are simple mixtures of water, salts, and sugars designed to prevent and treat dehydration, especially due to diarrhea or vomiting. They help replenish lost fluids and electrolytes, making them effective for both children and adults. ORS is easy to prepare and can be made at home or purchased in pre-packaged forms. The key components of ORS include sodium, potassium, and glucose, which work together to enhance water absorption in the intestines. This solution is recommended by health organizations like the World Health Organization (WHO) as a vital tool in managing dehydration, particularly in areas with limited access to medical care.
